MCPTT Load Tester

Simulates mobile radios to test MCPTT equipment.

Overview

The Valid8 MCPTT tester enables testing of SIP, Diameter and RTP on the LTE network.

What It Can Do For You

Scalable MCPTT SIP, Diameter, RTP load and feature testing.

Test MCPTT equipment and public safety networks with realistic traffic.

Why It’s Different

  • Software based solution can be run on high-end customer hardware/VM to achieve better performance, or in the Cloud (e.g. Amazon AWS) for maximum versatility
  • Web-based Graphical User Interface provides customer with intuitive, easy access via browser
  • API’s used (REST, HTTP)  enable automated testing using test tools.
  • Emulated nodes behave exactly as true real nodes, due to Finite State Machine architecture
  • Testing is scalable across multiple cores and multiple systems

Features

  • Tests MCPTT AS
  • Measure Key Performance Indicators (KPIs) such as number of simultaneous sessions and Busy Hour Call Attempts (BHCA)
  • Check power-on, registration, and PTT voice calls
  • Registration load
  • RTP media file playback
  • Report on media received, call connect time, call duration, jitter, packet loss
  • Generate valid and invalid/negative messages and call-scenarios
  • Supports sending invalid responses including malformed, dropped and misordered packets
  • Alerts and notifications

Subsystems

The Valid8 MCPTT tester is compromised of multiple subsystems that are available individually or in parallel, and are scalable to fit your needs. The individual emulators are controllable through their call controllers, and the traffic can be captured through use of a remote capture tool such as Wireshark.

  • UE Client
  • HSS
  • Server

KPIs
  • Call Setup Time
  • Post Dial Delay
  • Post Pickup Delay
  • Call Teardown Time
  • Media Delay
  • MCPTT Access Time
  • End-to-end Access Time
  • Mouth-to-Ear latency
Configurable Parameters
  • ‍Call session length
  • Concurrent calls/endpoints
  • BHCA/CPS

Automation API

User commands can be fully automated using REST API. This includes performing all test control functions as well as collecting results and metrics.

Scripting

The application’s subsystems can be edited directly in the browser using Javascript or by using the graphical tools seen below. The Message Workshop allows for creating of test scenarios directly from the hex stream of a remote capture, while the Graphical Editor allows for creating customized call scenarios by dragging and dropping the call flow to meet your test needs.
